Question

A particle moves along the x – axis form x = 0 t x = 5m influence of force given by F = 7 – 2x + 3x². Calculate the work done in doing so.

Answer 1

Work done to displace the particle by a force F through a distance dx is given by dW = F dx. 

Total work done to displace the particle from x = 0 to 5m is given by x = 5
